Title: How to troubleshoot artifacts and skipping [Solved - bad file]
Post by: eezetee on March 13, 2016, 10:58:46 pm

I've got an i7 server that houses a few WD 6TB Red drives over a cat6 LAN in my house.  The devices I use to connect are LAN wired.  They range from an old acer to an Intel i5 NUC (Meaning low specs to pretty high desktop type specs in small form factor)

I was playing some movies that I have on the server in JRiver and there were artifacts (big square blobs) and the scene would often jump. This happened on 2 different devices.

How can I go about troubeshooitng this?  Should I choose on problem movie, analyze it and see what the issue is with it or are there diagnostics tests I can do?  AVI is the file I was just testing from my Android phone using EOS and it showed the same artifact blobs/squares.

Many thanks!

If the client machine has the drive space, copy a movie to it for testing, to see if it plays correctly that way - to eliminate the network from the troubleshooting. Also try watching the movie with the Windows Resource and/or Performance Monitor open so you can see if the CPU, Memory or Disk performance is showing a problem.

Try playing in other players.  The file may be bad. 

Or the LAN may not be fast enough.

Try setting MC video to Red October Standard.

Here are the steps. It appears to not be a JRiver problem.

Copied the file over the LAN to the device. 75MB/sec.  Not a LAN problem
Tried to open the file in Windows Media Player --  WMP cannot open it.
Use MediaInfo ( see attached image) and saw it was a DivX file, possibly an old codec.
Tried to open the file in VLC and it warned of a corrupt/missing Index.

Seems to be just a bad file.

Would be nice to see JRiver with some test options built in to see if BlueRay/DVD streaming works, test various codecs, etc.
